Laser engravers use the power of light to remove material from an object. The laser puts out a small beam of light, which heats up a small part of the material. When it gets hot enough, the material will vaporize, which leaves an engraving. Since the laser is very small, this allows for far more precise engraving than most other methods. It’s also much easier than convention engraving, because a computer can do most of the work.
Laser engravers can work on a wider variety of materials than most other engraving tools. They’re most often used on wood and metal, but some people also use them on plastic or even rubber. The engravers can even be used on glass to create a unique fractured pattern, which is impossible to reliable create with any other engraving tool.
They Work Quickly
Laser engravers can create precise designs in a shockingly small amount of time. There are several factors that contribute to their speed. Laser engravers are computerized, so they never have to stop and think about their work before they continue. They also make very few mistakes, so they don’t need to spend as much time checking their work as a human engraver. Since lasers rely on heat to eliminate material, they also produce less waste than conventional engraving, which reduces the time that needs to be spent on cleaning up after the project has finished.
They Minimize Training
It takes a long time to train someone to engrave using traditional tools. It takes even longer to train an engraver who can follow a pattern as accurately as a laser engraver. That having been said, creating a pattern for the laser engraver to follow does take some training. The systems rely on CAD to produce a pattern that the machine can understand. Once a person understands CAD, they can create almost any pattern that they need, but reaching that point takes time. Fortunately, CAD training is becoming more common as the number of programs that rely on it increases, so it’s easy for a business to find designers.
They’re Not Just for Decoration
People think of engraving as a decorative art, but it also has practical applications. A laser engraver can cut materials so that they fit together very tightly, which has many applications in manufacturing. They can also produce stamps and other useful devices that depend on having a specific shape.
They’re Still Improving
All of these benefits mean that the laser industry is growing quickly. That’s a good thing for consumers, since laser manufacturers can afford to put more money into research, which leads to better engravers. The speed, efficiency, and precision that these devices have to offer is getting better every day, and as likely to continue to do so for a long time to come.
